Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2018-20455)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a stack-based buffer overflow) by crafting an input file, a related issue to CVE-2018-20456. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Stack-based buffer overflow (CVE-ID: CVE-2018-20456)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a stack-based buffer over-read) by crafting an input file, a related issue to CVE-2018-20455. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Out-of-bounds read (CVE-ID: CVE-2018-20458)

The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

In radare2 prior to 3.1.1, r_bin_dyldcache_extract in libr/bin/format/mach0/dyldcache.c may allow attackers to cause a denial-of-service (application crash caused by out-of-bounds read) by crafting an input file.


4) Out-of-bounds read (CVE-ID: CVE-2018-20461)

The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

In radare2 prior to 3.1.1, core_anal_bytes in libr/core/cmd_anal.c allows attackers to cause a denial-of-service (application crash caused by out-of-bounds read) by crafting a binary file.


5) Out-of-bounds read (CVE-ID: CVE-2018-19843)

The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

opmov in libr/asm/p/asm_x86_nz.c in radare2 before 3.1.0 allows attackers to cause a denial of service (buffer over-read) via crafted x86 assembly data, as demonstrated by rasm2.
